Answer:
1: The one vertical from 104° is 104°
2:The one near the corner is 20°
3: The two angles right next to 104° are 76°
Step-by-step explanation:
1: Vertical angle are always equal to each other.
2: All sides of the triangle must equal 180° in all. If you add 56° + 104° it equals 160°. Now subtract 180° - 160°. You get 20°.
3: All straight angles equal 180° in all. So, if you subtract 180° from 104° you will get 76°. And again, these two angles are vertical so they will both be 76°.
